Field Documentation

struct coap_async_state_t* coap_context_t::async_state

list of asynchronous transactions

Definition at line 83 of file net.h.

coap_endpoint_t* coap_context_t::endpoint

the endpoint used for listening

Definition at line 91 of file net.h.

coap_opt_filter_t coap_context_t::known_options

Definition at line 77 of file net.h.

unsigned short coap_context_t::message_id

The last message id that was used is stored in this field.

The initial value is set by coap_new_context() and is usually a random value. A new message id can be created with coap_new_message_id().

Definition at line 114 of file net.h.

ssize_t(* coap_context_t::network_read) (coap_endpoint_t *ep, coap_packet_t **packet)

Definition at line 129 of file net.h.

ssize_t(* coap_context_t::network_send) (struct coap_context_t *context, const coap_endpoint_t *local_interface, const coap_address_t *dst, unsigned char *data, size_t datalen)

Definition at line 124 of file net.h.

unsigned int coap_context_t::observe

The next value to be used for Observe.

This field is global for all resources and will be updated when notifications are created.

Definition at line 120 of file net.h.

struct coap_resource_t* coap_context_t::resources

hash table or list of known resources

Definition at line 78 of file net.h.

coap_response_handler_t coap_context_t::response_handler

Definition at line 122 of file net.h.

coap_queue_t* coap_context_t::sendqueue

Definition at line 90 of file net.h.

coap_tick_t coap_context_t::sendqueue_basetime

The time stamp in the first element of the sendqeue is relative to sendqueue_basetime.

Definition at line 89 of file net.h.

int coap_context_t::sockfd

send/receive socket

Definition at line 94 of file net.h.
